Whew Tony, sounds like you've got your ducks in a row alright!!
My set-up is as follows...
3.1 liter L28 w/ cast pistons 8.5:1 compression ... (no detonation, no problems)
440cc R/C injectors
Mercedes 67.5 mm throttlebody, ported and powdercoated 75 intake
Ported and polished P90A head, swirl polished valves, performance valve springs, new hydraulic rockers, and stock turbo cam
T3/T4 hybrid turbo
Turbo X/S BOV
Scottie's SS downpipe w/ 2.5" mandrel bent exhaust
Bosch 95psi pump
NPR intercooler w/ 2.5" tubing
SDS engine management
83 stock turbo clutch
77 5-speed
3:54 rear
I have driven the car back and forth from the welding shop, but haven't begun to tune the SDS yet. I haven't run it with any boost yet either. I just placed an extra air filter on the t/b to get it there and back.
Initially I plan on keeping it under the 300 hp range (I'm a bit paranoid about throwing a bunch of boost at a new engine.) After a good break-in, I hope to eclipse the 350 hp mark.
I like the idea of a Supra powered Z. My set-up is currently in a 77Z. It isn't much to look at, but the frame was solid, so it makes a good guinea pig for me.
Living in Fla, we haven't any smog test, state inspections, etc...which can be both good and bad... anyway, I also have a 71 body which I have replaced practically the whole uni-body. When I finish with the body work, it may see this drivetrain...or maybe a Supra 2JZ...???
